PORT ST. LUCIE — Manager Jerry Manuel can envision a roster that includes both of the Mets’ Japanese imports.

The manager watched Ryota Igarashi and Hisanori Takahashi throw morning batting practice, and seemed impressed by the ability of both to throw strikes. Manuel’s battle cry this spring is for all his pitchers to throw strikes.

The right-hander Igarashi — who features a split-fingered fastball — figures to compete for the setup role while the left-hander Takahashi could be a swingman.
